Description
1) DOMAINE DE L'INVENTION1) FIELD OF THE INVENTION
La présente invention concerne une roue de valise qui est du type utilisé avec les valises normales mais dont le but principal est de permettre à la roue de conserver une direction fixe de progression qui n'oscille pas de part et d'autre lorsqu'on fait avancer la valise. The present invention relates to a suitcase wheel which is of the type used with normal suitcases but whose main purpose is to allow the wheel to maintain a fixed direction of progression which does not oscillate on either side when doing advance the suitcase.
2) DESCRIPTION DE L'ART ANTERIEUR2) DESCRIPTION OF THE PRIOR ART
Dans les valises de conception traditionnelle, on trouve en général deux ou quatre roues qui sont montées en bas de la valise non seulement pour supporter celle-ci mais encore pour économiser les forces de l'utilisateur lorsque celui-ci exerce une traction pour déplacer la valise. Sur les figures 1 et 2, on a représenté une roue de valise normale. La roue comprend un roulement monté à l'intérieur de la partie supérieure de la roue. Cette partie de la roue n'étant pas l'objet de la présente invention, on ne la décrira pas plus en détail, un support de roue 2 et une roue 3. In suitcases of traditional design, there are generally two or four wheels that are mounted at the bottom of the bag not only to support it but also to save the user's forces when it exercises traction to move the suitcase. In Figures 1 and 2, there is shown a normal bag wheel. The wheel includes a bearing mounted within the upper portion of the wheel. This part of the wheel not being the subject of the present invention, it will not be described in more detail, a wheel support 2 and a wheel 3.
Pour cela on réalise dans la partie centrale avant du support de roue 2, une rainure 21 de telle manière que la roue 3 puisse être montée à l'intérieur de la rainure. La roue 3 est montée dans la rainure 21 à l'aide d'une goupille de liaison 31. En raison du roulement monté à la partie supérieure du support 2, lorsqu'on exerce une traction sur le corps de la valise et s'il faut effectuer un changement de direction, le support 2 peut tourner en créant un changement relatif de direction par rapport à la roue 3 pour réaliser l'effet de roulement de la roue 3. For this purpose, a groove 21 is formed in the central front part of the wheel support 2 so that the wheel 3 can be mounted inside the groove. The wheel 3 is mounted in the groove 21 by means of a connecting pin 31. Due to the bearing mounted at the upper part of the support 2, when a traction is exerted on the body of the case and if must be made a change of direction, the support 2 can rotate by creating a relative change of direction relative to the wheel 3 to achieve the rolling effect of the wheel 3.
Cependant, comme la roue est équipée d'une seule roue 3 et que la partie supérieure de la roue comporte un roulement libre en rotation, la roue ne conserve pas une direction fixe de déplacement de telle sorte que lors d'une action de traction, le déplacement de la valise est soumis à des agitations d'un côté et de l'autre et ainsi la traction ou la poussée exercée sur la valise devient difficile et doit être améliorée. However, as the wheel is equipped with a single wheel 3 and the upper part of the wheel has a free rotation of rotation, the wheel does not maintain a fixed direction of displacement so that during a traction action, the displacement of the bag is subject to agitations on one side and the other and thus the traction or the thrust exerted on the bag becomes difficult and must be improved.
De plus, au moment du déplacement de la valise, lorsque l'utilisateur a besoin de prendre l'ascenseur ou de la déplacer sur un terrain incliné, il est souhaitable que la valise puisse être arrêter temporairement alors que les roues de valise classiques ne comportent pas de moyen de freinage dans une direction fixe. En conséquence, l'utilisateur doit serrer fortement la poignée de la valise pour éviter que celle-ci ne glisse. In addition, when moving the bag, when the user needs to take the elevator or move it on inclined ground, it is desirable that the bag can be temporarily stopped while the conventional baggage wheels do not include no braking means in a fixed direction. As a result, the user must strongly tighten the handle of the bag to prevent it from slipping.
3) OBJET DE L'INVENTION Un objet de la présente invention est de fournir une roue de valise pour remédie aux inconvénients énoncés ci-dessus. 3) OBJECT OF THE INVENTION An object of the present invention is to provide a suitcase wheel to overcome the disadvantages mentioned above.
Pour atteindre ce but, la roue de valise selon l'invention comprend: - un support - un roulement à la partie supérieure du support; et - une roulette et elle se caractérise en ce que: - les deux côtés avant du support sont reliés respectivement à une roulette et la partie centrale avant du support comporte une rainure pour la mise en place d'une roulette auxiliaire tournante; et - le diamètre de la roulette auxiliaire est inférieur à celui des roulettes, la roulette auxiliaire étant fixée à l'aide d'une goupille de liaison. To achieve this purpose, the suitcase wheel according to the invention comprises: - a support - a bearing at the upper part of the support; and - a wheel and it is characterized in that: - the two front sides of the support are respectively connected to a wheel and the front central portion of the support comprises a groove for the establishment of a rotating auxiliary wheel; and - the diameter of the auxiliary wheel is less than that of the wheels, the auxiliary wheel being fixed by means of a connecting pin.
On comprend que grâce aux dispositions de l'invention, lorsque l'utilisateur veut déplacer la valise pendant un certain temps en inclinant le corps de celle-ci selon un angle convenable, le dispositif de roue assure une progression de la valise dans une direction fixe sans déplacements latéraux. It is understood that, thanks to the provisions of the invention, when the user wants to move the bag for a certain time by tilting the body thereof at a suitable angle, the wheel device ensures a progression of the bag in a fixed direction without lateral movements.
De préférence, la roue de valise comprend en outre: - une rainure circulaire ménagée dans chaque roulette dans leur face tournée vers le support, chaque rainure circulaire comportant des encoches; - un trou de fixation ménagé dans le support pour recevoir une goupille de commande et un coussinet à ressort; et - une pièce de freinage munie à son extrémité d'un trou ovale apte à recevoir ladite goupille de commande de telle manière que la pièce de freinage soit montée à l'avant dudit support et que les deux extrémités de la goupille de commande puissent pénétrer dans ladite rainure circulaire de chaque roulette et que la goupille de commande puisse être pressée par ledit coussinet à ressort dans lesdites encoches pour former un système de freinage. Preferably, the suitcase wheel further comprises: - a circular groove formed in each wheel in their face facing the support, each circular groove having notches; a fixing hole formed in the support for receiving a control pin and a spring pad; and a braking piece provided at its end with an oval hole capable of receiving said control pin in such a way that the braking part is mounted at the front of said support and that both ends of the control pin can penetrate in said circular groove of each wheel and that the control pin can be pressed by said spring pad into said notches to form a braking system.
On comprend que, grâce au système de freinage, lorsque la valise est par exemple dans un ascenseur, les roues de la valise peuvent être immobilisées efficacement sans glissement de celles-ci par rapport au sol de l'ascenseur. It is understood that, thanks to the braking system, when the case is for example in an elevator, the wheels of the bag can be immobilized effectively without sliding thereof relative to the floor of the elevator.

5) DESCRIPTION DETAILLEE DE MODES PREFERES DE REALISATION DE L'INVENTION En se référant tout d'abord aux figure 3 et 4, on voit que la roue de valise, objet de l'invention est constituée en partie supérieure par un support 4 et des roulettes 5. L'objet de l'invention est de relier les deux côtés des extrémités du support aux roulettes 5 et de ménager dans la partie centrale avant du support 4 une rainure 41 pour placer une roue rotative auxiliaire 6, le diamètre de cette roue auxiliaire étant inférieur à celui des roulettes 5, la roulette auxiliaire étant montée à l'aide d'une goupille de liaison 61. 5) DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Referring firstly to FIGS. 3 and 4, it can be seen that the suitcase wheel, object of the invention, is constituted in the upper part by a support 4 and casters 5. The object of the invention is to connect the two sides of the ends of the support to the wheels 5 and to arrange in the central front portion of the support 4 a groove 41 to place an auxiliary rotating wheel 6, the diameter of this wheel auxiliary being lower than that of the rollers 5, the auxiliary wheel being mounted by means of a connecting pin 61.
Les figures 5A, 5B, 5C, 5D et 5E montrent l'organisation de l'invention. Comme le support de roue 4 est relié des deux côtés aux roulettes 5, la roue de valise peut surmonter les inconvénients mentionnés ci-dessus et remédier à l'insuffisance produite par une roue de valise traditionnelle. En effet, on obtient un effet plus stable lors de l'avancement de la valise selon une direction fixe et lorsqu'il est nécessaire de déplacer la valise en lui donnant un certain angle pendant un certain temps, la roue auxiliaire 6 qui est disposée dans la partie centrale avant du support 4 entre en contact avec le sol (comme le montre la figure 5B) quand le corps de valise est incliné d'un angle convenable, cette roulette auxiliaire 6 peut former un point d'appui (voir figures 5C et 5D) avec une fonction de roulement à l'intérieur de la partie haute du support 4, ce qui permet de provoquer la rotation complète de la roue d'un angle de 180 (comme le montre la figure 5E), de telle manière que la roue puisse avancer selon une direction fixe. Figures 5A, 5B, 5C, 5D and 5E show the organization of the invention. As the wheel support 4 is connected on both sides to the wheels 5, the wheel suitcase can overcome the disadvantages mentioned above and remedy the deficiency produced by a traditional wheel suitcase. Indeed, a more stable effect is obtained during the advancement of the bag in a fixed direction and when it is necessary to move the bag giving it an angle for a certain time, the auxiliary wheel 6 which is arranged in the front central part of the support 4 comes into contact with the ground (as shown in FIG. 5B) when the luggage body is inclined at a suitable angle, this auxiliary wheel 6 can form a fulcrum (see FIGS. 5D) with a rolling function inside the upper part of the support 4, which makes it possible to cause the complete rotation of the wheel by an angle of 180 (as shown in FIG. 5E), so that the wheel can move in a fixed direction.
De plus, les figures 3, 4, 6A, 6B, 6C, 7A, 7B et 7C montrent que les bords intérieurs des roulettes 5 tournées vers le support 4 sont pourvus chacun d'une rainure circulaire 51. Un trou de fixation 42 est ménagé au centre du support 4 pour fixer un coussinet à ressort 43 dans ce trou. La roue de valise est équipée d'une pièce de freinage 44 montée des deux côtés de la partie centrale du support 4. Un trou ovale 441 est réalisé à l'extrémité de la pièce de freinage 44. La goupille de commande 45 comporte une rainure circulaire 451 en son centre qui peut passer dans le trou 441, et le trou 42. Les deux extrémités 452 de la goupille de commande 45 peuvent pénétrer dans les rainures circulaires 51 ménagées à l'intérieur des roulettes 5 et la rainure de fixation 451 est pressée par le coussinet à ressort 43 qui est monté à l'intérieur du trou 42 constituant ainsi une structure de freinage. In addition, FIGS. 3, 4, 6A, 6B, 6C, 7A, 7B and 7C show that the inner edges of the rollers 5 facing the support 4 are each provided with a circular groove 51. A fixing hole 42 is provided in the center of the support 4 to fix a spring pad 43 in this hole. The bag wheel is equipped with a braking piece 44 mounted on both sides of the central portion of the support 4. An oval hole 441 is formed at the end of the braking piece 44. The control pin 45 has a groove circular 451 at its center which can pass in the hole 441, and the hole 42. The two ends 452 of the control pin 45 can enter the circular grooves 51 formed inside the rollers 5 and the fixing groove 451 is pressed by the spring bearing 43 which is mounted inside the hole 42 thereby constituting a braking structure.
Lorsque l'utilisateur de la valise veut prendre l'ascenseur ou emprunter une zone inclinée qui nécessite l'immobilisation temporaire de la valise, il peut presser vers le bas la pièce de freinage 44 à l'aide du pied de telle sorte que le coussinet à ressort 43 monté à l'intérieur du trou 42 du support 4 agisse sur la goupille de commande 45 disposée à l'extrémité de la pièce de freinage 44. Le coussinet à ressort 43 pousse la goupille de commande 45 vers le haut de telle manière que les deux extrémités 452 de la goupille de commande 45 entrent dans une encoche 511 de la rainure circulaire 51 ménagée dans les roulettes 5. Ainsi, la roue de valise se trouve immobilisée (voir figures 6A, 6B et 6C). Au contraire, si l'on veut déplacer à nouveau la valise, la force de traction appliquée aux roulettes 5 fait que les deux extrémités 452 de la goupille de commande 45 sortent des encoches 511 de la rainure circulaire 51. Les roulettes 5 se trouvent alors libérées et peuvent tourner (voir figures 7A, 7B et 7C). When the user of the bag wants to take the elevator or take an inclined zone that requires the temporary immobilization of the bag, he can press down the braking piece 44 with the foot so that the pad spring 43 mounted inside the hole 42 of the support 4 acts on the control pin 45 disposed at the end of the braking piece 44. The spring-loaded pad 43 pushes the control pin 45 upwards in such a manner that the two ends 452 of the control pin 45 enter a notch 511 of the circular groove 51 formed in the rollers 5. Thus, the bag wheel is immobilized (see Figures 6A, 6B and 6C). On the contrary, if it is desired to move the bag again, the traction force applied to the rollers 5 causes the two ends 452 of the control pin 45 to come out of the notches 511 of the circular groove 51. The rollers 5 are then released and can rotate (see Figures 7A, 7B and 7C).
Il découle de la description précédente, que la présente invention permet effectivement de palier aux insuffisances des roues de 5 valise du même type connu. It follows from the foregoing description that the present invention effectively makes it possible to overcome the insufficiencies of the suitcase wheels of the same known type.
